Additional notes:     

• Taxonomy 

  • The Australian botanist Norman Byrnes has noted that Homoranthus "is not a clearly defined natural group but is more a genus of convenience between Darwinia and Verticordia

  • In 1869, George Bentham wrote "Its retention [as a separate genus] may, however, be justified as facilitating the distinction between Darwinia and Verticordia"

  • The genus Homoranthus was first formally described in 1836 by Johannes Conrad Schauer after an unpublished description by Allan Cunningham

  • Schauer's description was published in Linnaea: ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkunde
